Marine piling of different characters such as "wood, metal,-or concrete will deteriorate after they have been placed in the water due to the action of the water, or to sea growth or sea animals, so that it is necessary to repair them in someway. As an example, I- will use concrete piling about which it is necessary to place a sheath or coating of concrete or cement to further strengthen and reinforce the same. The repairs to the pile extend from a fewfeet below the low water line to about the high water line and heretofore the, difliculty has been to reach the piling below the water and effectively work upon. this area.

An object of my invention isto provide a marine cage which can be placed around. the

iling and partly submerged so that the afected area of the piling can be reached and worked.

Another object is to provide a marine cage which-can be quickly and easily emptied of water after it is in position and can be kept dry while the workmen are working on the pile;

1 Still another object is to provide a marine cage which can beeifectively held partly submerged and this holding means also serves to seal off the water from the inside of the cage.

. Other objects, advantages, and features of invention may appear from the accompanying drawings, the subjoined, detailed description, and the appended claims.

In the drawings Figure 1 is a longitudinal sectional view of my cage in position around a pile.

Figure 2 is an enlarged fragmentary vertical view of the lower end of the cage.

Figure 3 is a side elevation of the cage on a reduced scale.

Figure 1 is an enlarged fragmentary horizontal sectional View of the bottom of the ca e.

Figure 5 is an enlarged horizontal sectional view of the door seal.

Figure 6 is an enlarged horizontal sectional view .of'the hingeseal.

Referring more particularly to the drawings, my cage comprises a metal housing 1 open at the top, the housing being of such diameter that workmen can readily be. accommodated therein and may operate upon the pile2 around which the cage is placed. A door 3 is provided in the side of-the housing 1 and this door is hinged at 1.

A fibrous or rubber strip 5 is secured longitudinally of the hinge and one side of the strip 5 is secured to the housing 1 and' the other to the door 3. Thus the hinge is effectively sealed against leakage. The swinging end of the door is provided with a flange 6, said flange being complementary to a flange 7' secured to the housing 1. A packing is secured between the'two flanges and a plurality of bolts 9 extend through the flanges and hold the packing 8 in position. Thus the swinging end of the door is prevented from leaking.

A circular opening 10 is provided in the bottom of the housing 1 and centrally thereof and the piling 2 extends throu h this opening. A bottom door 11 exten s from the central opening 10 to the outer periphery of the housing 1 and this door is also provided with a packed hinge 12 and a sealed swinging end 13 of the same character as previously described for the door 3. The marine, cage is placed around the piling by opening the doors 3, 11 inserting the piling through these doors, and then closing and bolting both of the doors.

In order that the cage may be applicable to various sizes of piling the opening 10 is made larger than the piling and a plate 14 is dropped over the piling and fits closely about the same, this plate serving to close the opening 10. A plastic or cement seal 15 is then poured around the piling 2 and upon the plate 14, thus sealing the bottom of the cage. I

A displacement chamber 16 is provided in the bottom of the cage, the purpose ofwhich will be further described. The inner walls of the chamber 16taper outwardly, as shown at 17 and these walls serve to confine the seal 15 and bear against said seal to prevent the cage from moving upwardly due to the buoyancy thereof after the water has been removed from the cage. A valve 18 is provided in the bottom of the chamber 16 and a second-valve 19 is provided in the top of the chamber, the last named valve opening into the housing 1. A pipe 20 rises from the pipe 19 and an operating handle 21 is pivotally secured to the top of the pipe. A rod 22 rises from the valve 18 and extends upwardly through the pipe 20. An operating handle 23 is secured to the top of the rod 22.

Water is removed. from the inside of the cage in the following manner: The valve 18 is closed and the valve 19 is opened, thus permitting water to drain from the inside of the cage into the displacement chamber 16. The valve 19 is now closed and the valve 18 opened. Air under pressure is introduced into the tube 20 through the pipe 24, the air passing downwardly through the tube and through the valve 19 displacing the water in the displacement chamber and forcing the water out past the valve 18. When the water is removed the valve 18 is against closed and the operation repeated.

For the purpose of more conveniently placing the seal 15 a grouting tube 25 rises from adjacent the top of the displacement chamber 16 and extends above the normal water level in the housing. A scaffolding 26 is provided approximately midway of the housing 1 upon which the workmen can stand to work upon the upper areas of the piling.

My cage is assembled around the pile before it is partially submerged,jthat is, the doors 3 and 11 are closed after which the cage is lowered to the required point, then in order to hold the cage in this position a plurality of stabilizing screws 27 are provided, said screws extending through blocks 28 which are secured to the top of the displacement chamber or upon the sea-Holding 26. These screws engage the pile 2, as shown in Figure 1, and prevent the housing from moving upwardly while the seal 15 is bein placed. After the seal is in position and has hardened the water is removed from the housing, as previously described, after which the workmen enter the cage and the worl: on the pile commences.

A plurality of hook bolts or lugs 29 are provided on the housing 1 for the purpose of transporting itfrom one pile to another. Outwardly curved wave deflecting sections 30 are provided at the top of the housing 1 for the purpose of deflecting a wave out wardly and keeping the water from coming over the top of the housing.

The arrangement of my displacement chamber is such that it can be easily operated at any time without inconveniencing the workmen in event there is a slight leakage into the cage, or it may be continuously operated if necessary. The buoyant effect of the housing is counteracted'by the tapered walls 17 bearing upon the cement seal 15, this seal being in vertical sheer and is of sufiicient strength to overcome the upward thrust.

Having described my invention, I claim:

1. A marine cage adapted to be placed around a pile and comprising a housing open at the top, said housing having an opening in the bottom thereof through which the pile extends, a door in the side of said housing, a second door in the bottom of the housing, the cage being adapted to be assembled around the pile through said doors, means to seal the bottom opening of the housing around-the pile, and means whereby the water may be removed from within the housing.
